Muay Thai Training

Long time fan, first time post - so I'm prepared to get skinned alive for asking questions on previous threads. That being said...

If anyone can give solid tips on Muay Thai training I would be forever greatful; you might even be the recipient of my "eternal gratitude". I'm looking for your best tips on weight training, cardio, and nutrition. I've got to preface that I'm somewhat against supplementation, but if they work for you, lemme know how you roll.

First reply gets a free ice-cream sandwhich. Wow, those things are tastey.
